Module development and code questions

I have a module that queries for a specific webform submission data and sends an array of the results to the view. 
When I dpm the array before the return, it shows what I would expect. An array of strings. In my view, I am getting only one field object and it is the first letter of each element in my array. I was expecting to see a field list of each element in the array

Hi, I am trying to run a query in a custom module to get submissions from a web form. I am new to Drupal and Drupal database queries; but not new to databases and queries. My queries work in phpMyAdmin. I am working on a project that is in Drupal 7. I have tried many examples from Drupal documentation but every query I try I get:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'FROM node node' at line 3

I am working on adding Migrate support to the Poll module. Progress and patches can be seen in this issue: https://www.drupal.org/project/poll/issues/2638406

Hi all,

I have created 2 custom content types. The first (i.e. A) has three entity reference fields of the second content type (B).

In my custom module, I am trying to set the values of some fields of B when adding a new A content, but the

$form['field_my_B_1_field']['widget'][0]['inline_entity_form']['#default_value']

is null in the 'my-module_form_alter' hook.

Pleaseeeee, how do i get to set the values of the entity reference fields on a new form (the one when adding a new node of content of type A) ?

Thank you in advance.

Hi All,

Whats the best way to learn drupal module development?

I am guessing this comes up a fair bit.  But if I was looking to learn drupal 8 module development, does anyone have any recommendations for books to learn from?  Or am I better off with online courses?

I am currently going through the freecodecamp tutorials (which don't cover PHP nevermind drupal module dev).  Therefore I am a complete new comer to Drupal (although I did dabble making a module under Drupal 5),

Any advice highly appreciated!

Thanks in advance,

Mark.

Hi,

I am trying to add a "Save & Send Email" button to both the Node Add and Node Edit forms of a Content Type to give the Current User the option of sending themselves an email after saving the content.  I have put together code that works to add the button and to generate the email, but I cannot figure out how to have the button (#submit) trigger sending the email.  Could someone please help me tie them together?  I am also not sure how (if?) to implement both the hook_entity_insert and hook_entity_update in the same module.  The code I have so far is:
